The control circuit board 100 comprises a processor 10, an analog front end 20, a communication module 30, a power supply circuit 40, an output circuit 50 and a printed circuit board 60; the analog front end 20 is electrically connected with the processor 10, used for collecting parameters of the battery 210 and controlling the conduction or disconnection of the switch circuit 220 based on the parameters; the communication module 30 is electrically connected with the processor 10; the power supply circuit 40 is used for supplying power to the processor 10 and the communication module 30; the output circuit 50 is electrically connected with the processor 10 and connects the battery 210 through the switch circuit 220, the processor 10 controls the output circuit 50, the processor 10 controls the electrical connection and output power of the output circuit 50 with external circuits; the processor 10, the analog front end 20, the communication module 30, the power supply circuit 40 and the output circuit 50 are all arranged on the printed circuit board 60.

[0026] In the control circuit board 100 of the embodiment, the processor 10, the analog front end 20, the communication module 30, the power supply circuit 40, and the output circuit 50 are essential components of the energy storage power supply 200. The processor 10, the analog front end 20, the communication module 30, the power supply circuit 40, and the output circuit 50 are all arranged on the printed circuit board 60. In this way, when the discharge power of the energy storage power supply 200 needs to be changed, the development of a separate main board and a protection board can be omitted, and the development efficiency of the energy storage power supply 200 is improved. In addition, the same circuit can be verified repeatedly, the development efficiency is improved, and the possibility of design errors is reduced. In addition, the control circuit board 100 can avoid subsequent electromagnetic compatibility test interference, and is convenient for after-sales maintenance.

[0027] Specifically, the control circuit board 100 is a control component of the energy storage power supply 200, and the control circuit board 100 can control the charging and discharging of the energy storage power supply 200. The processor 10 can be a microprocessor 10 (Micro controller unit, MCU), and the processor 10 can monitor functions such as the on-off control, charging and discharging control, protection function control, and state of the energy storage power supply 200.

[0028] The analog front end 20 (Analog Front End, AFE) can also be an AFE chip. The AFE chip is an integrated circuit that serves as a connection point between a sensor and a digital signal processor 10, and is mainly responsible for processing analog signals and converting them into digital signals. The AFE is a core component of the energy storage power supply 200.

[0029] In one example, the analog front end 20 can collect parameters such as the voltage, temperature, and current of the battery 210 of the energy storage power supply 200, and upload the collected data to the processor 10. When the corresponding function button of the external panel of the energy storage power supply 200 is pressed, the analog front end 20 is awakened, and at the same time, the analog front end 20 controls the charging and discharging MOS to be closed. After the voltage, temperature, and current data of the battery 210 of the energy storage power supply 200 are collected, they are uploaded to the processor 10. The processor 10 determines whether the state of the battery 210 is normal through these data, and issues corresponding instructions to the analog front end 20 to control the operation of the battery 210.

[0030] The communication module 30 is a combination of elements for communication and interaction between the control circuit board 100 and other components of the energy storage power supply 200 or external devices. For example, the control circuit board 100 can exchange data with other components of the energy storage power supply 200 or external devices through the communication module 30.

[0031] The power supply circuit 40 can convert the voltage and / or current provided by the power supply into voltage and / or current matching the processor 10 and the communication module 30, so that the processor 10 and the communication module 30 can work normally. For example, the power supply circuit 40 can provide 3.3V voltage to the processor 10 and 5V voltage to the communication module 30.

[0032] The output circuit 50 can be a circuit for realizing low-power output externally. For example, the processor 10 can provide power to the display screen and other power-consuming components of the energy storage power supply 200 through the output circuit 50.

[0035] In some embodiments, the WiFi module and the Bluetooth module 32 are arranged at different corners of the printed circuit board 60. In this way, when the WiFi module and the Bluetooth module 32 communicate, the interference between the WiFi signal and the Bluetooth signal is small, which can improve the communication quality. For example, Figure 2 In the example shown in the figure, the WiFi module is arranged at the upper left corner of the printed circuit board 60, and the Bluetooth module 32 is arranged at the lower right corner of the printed circuit board 60.

[0036] Referring to Figures 2-3 In some embodiments, the processor 10 is arranged close to the analog front end 20, the distance between the processor 10 and the analog front end 20 is a first distance L1, and the distance between the processor 10 and the power supply circuit 40 is a second distance L2. The first distance L1 is less than the second distance L2. In other words, compared with the power supply circuit 40, the processor 10 is closer to the analog front end 20.

[0037] Generally, the power of the processor 10 and the analog front end 20 is greater than the power of the power supply circuit 40. By arranging the processor 10 and the analog front end 20 close to each other, the electromagnetic compatibility design of the processor 10 and the analog front end 20 can be facilitated.

[0042] In some embodiments, the processor 10 has an I / O interface, and the processor 10 can add a voice module, a temperature sensor module, and a humidity sensor module through the I / O interface, and the processor 10 controls the voice module, the temperature sensor module, and the humidity sensor module.

[0043] In some embodiments, the discharge power range of the energy storage power supply 200 is 300W-3000W. For example, the discharge power of the energy storage power supply 200 can be 300W, 400W, 800W, 1000W, 2000W, 3000W, etc. It should be noted that the discharge power of the energy storage power supply 200 is the maximum discharge power of the energy storage power supply 200, and the energy storage power supply 200 can discharge at a power less than or equal to the maximum power.

[0044] The energy storage power supply 200 can be a portable energy storage power supply, so that the energy storage power supply 200 can be conveniently used.
